Use the GraphData to draw graphs

[lczhangmath (Licheng Zhang)]

Hello everyone;
As the function of GraphData[3] executes, outputs
the results shown below

 GraphData[3]
 {{"Empty", 3}, "P2+K1", {"Path", 3}, "TriangleGraph"}}

How to present these graphs of list of above?
Just like following graphs:

Thanks in advance for your help !

It looks like 3 is a class of graphs in GraphData, and so GraphData[3] returns the list of entities in that class. "P2+K1" is an actual graph entity, and GraphData["P2+K1"] gives its graph:

To get all of the graphs in the class you can use Map,

Map[GraphData, GraphData[3]]
